SIMEON SCHOON JACKSON, OF READVIL'LE, MASSACHUSETTS, ASSIGNOR TO THE STAFFORD COMPANY, OF READVILLE, MASSACHUSETTS, A CORPORATION OF NEW JERSEY.

To all whom 1' 23 may concern.

Be it known that l, SIMnoN Sermon JACK- soN, a citizen of the United States, residing at Readville, in the county of Norfolk, State of Massachusetts, have invented a certain new and useful Improvei'nent in Pick- Finder Devices for Looms, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention resides in piclctinder devices which are constructed and arranged to operate, in case of deficiency of weft, to cause the first pick after resumption of weaving with fresh weft to be introduced into a reopening of the proper shed to receive it, (3., in case of failure of weft, the shed in which such failure took place, in whichever direction of pick the failure occurred.

The invention provides for tripping automatic weft-replenishing instrumentalities into action, or for automatically tripping the shipper-devices to cause the driving-pmver to be unshipped to arrest the weaving action, or for tripping the said instrumentalities into action and in addition tripping the shipper devices so that the replenishing operations may be performed while the weaving operation is suspended, the loom being automatically restarted on the completion of the replenishing operations.

Embodiments of the invention may be variously constructed, arranged, and combined, and may be employed in looms using various numbers of harnesses and weaving goods with different numbers of shed-formations to the round or repeat of the pattern.

The atmimpanying drawings show an embodiment of the invention which is constructed and contrived for either three-harness weaving or five-harness weaving.

In the drawings,--ligure '1. of the drawings shows in side elevation a portion of a loom having an embodiment of the invention applied thereto, the parts being arranged to find the pick in three-harness weaving in case of failure of the weft or filling in a pick in either direction. Fig. 2, Sheet 2, is a front elevation of certain of the parts of Fig. 1. Fig. 3, Sheet 2, is a plan view of the parts of Fig. 2. Fig. 4t, Sheet 3, is a view in vertical section in the plane of the dotted lines 4, t, of Figs. 2 and 3, looking in the direction indicated by the arrows at the ends of such lines. Fig. 5, Sheet 3, is a detail view in section in the plane of the dotted Specification of Letters Iatent.

lines 5, 5, of Figs. 2 and 3, looking in the direction indicated by the arrows at the ends of such lines. Fig. (3, Sheet 3, and Figs. 7, 8 and 9, Sheet l, are views of the same parts as Fig. 5, showing them in successive positions assumed in operation. Fig. 10 is a view showing the positions of certain of the said parts during the stoppage of the loom. Fig. 11, Sheet 3, is a detail side elevation of the arm 26, tripping dog 27, and link 35). Fig. 12, Sheet 3, a similar view of the arm 28. Fig. 13, Sheet 2, shows the two cams by which the respective weft-hammers or goosenecks are actuated. Fig. 14, Sheet 5, is a detail viewshowing the adjustn'ient for fiveharness weaving. Fig. 15, Sheen, 5, is a diagram illustrating the operation in threeharness weaving when deficiency of weft or filling is detected in the pick toward the magazine side of the loom. Fig. 16, Sheet 5, is a diagram illustrating the operation when deficiency is detected in the pick toward the driving side of the loom.

Having reference to thc drawings,-A portion of one side-'lramc of a loom is represented at 1, Figs. 1, 2, 3, and l, and portions of the breast-beam are represented at 2, 2, Figs. 2, 3, etc. For the purpose of indicating the relation between the devices in which the invention more immediately resides and the power-eontrolling devices of the loom, the ship mr-handle 3 is represented in Figs. 1, 2 and 3, and the shipper rockshaft on which the shipper-handle is fixed indicated at t in the various views, and Figs. l, 2 and 23 show a portion of the length of the rod 5 through which the powershipping and brakcdeviuas not shown) are more immediately controlled from the shipper-handle. The said devices may be substantially as in U. S. Letters Patent No. 945,? 22, dated January 4, 1.910. The shipper-handle is shown in the position that is occupied thereby while the power is applied and the loom is running. To assist in showing one manner in which the pick-finder devices operate to arrest the taking-up of the woven cloth, and also cil'ect the letting-back of the cloth, the wm'm-gear of the take-up is shown at (3, Fig. 1, its actuating worm at 7, the rotating shaft on which such worm is fixed is shown at S, and a detentand letback pawl of well-known construction is shown at 9, the supporting stud therefor being indicated at 10, such stud beingcarried by the bearing 40 for the front end of the The said tripping rockshaft is supported by. a long bearing 11 Figs. 3'and 4c, forming part of a stand l1 attached to the front of the side-frame 1. It is shown provided with afinger 12, represented in Figs. 1 and 2, only a port-ion thereof being shown in the other views, the said finger being fixedly mounted by means of its hub or sleeve 12 upon the inner end of said rockshaft 11, at the inner side of bearing 11*. The finger is operatively combined, in practice, as in the case of the finger 13 of the Letters Patent aforesaid, with devices for automatically effecting replenishment of the working weftsupply, so that when'the tripping rockshaft and finger are turned the said devices are called into action and thereby the automatic replenishment is brought about. The precise character of the weft-replenishingdevices, or mode of operation thereof, is not material so far as the broad principlesof the invention are concerned, since such broad principles admit of being employed in connection with various types and constructions of devices of such class, whether contrivedto effect replenishment by insertion of a fresh weft-supply into a working shuttle on the lay of a loom, or by replacement of a spent or failed working shuttle by a fresh one. The replenishing devices and the connection of finger 12 therewith may be, for instance, as in the Letters Patent aforesaid. The tripping rockshaft 11 is shown provided also with alug 13,-Fig. 1, fixed by means of its hub 13 upon' the outer end of such rockshaft, at the outer side of bearing 11, and arranged to engage a lug or shoulder let on the shipper-handle By reason of such engagement, forward turning movement of the tripping rockshaft acts through the lugs 13 and 14 to operate the shipper-handle so as to unship the driving power ofthe loom and stop the weaving action. In some cases, the employment of automatic weft-replemshmg devices may be dispensed with, and after the loom has been stopped by the turning of the tripping rock-1 shaft the replenishment of the working weft-supply may be efiected by hand and the loom restarted by the weaver. So, also, in some cases, as when a dwell 1n the works ing of the loom is not required for the per-:

formance of the replenishing operations, the sald turnmg'movement may be utilized to call the replenishing devices into action" without effecting unshipping of the driving power and arrest of the weaving act-ion.

The particular arrangement of part-s that is shown in the drawings is more especially designed for employment in a replenishing loom of the well-known type in which the movement of finger 12 operates to trip a socalled change-shaft into rotation, at the same time that lug 13 trips the shipperhandle to unship the driving-power from the weaving instrumentalities and thereby suspend the weaving action, the changeshaft during its rotation actuating the vari ous replenishing instrumentalities to occasion replenishment during the suspension of the weaving action, and fin'allyrestoring the shipper-handle to its former position and shipping-0n the driving-power to resume weaving, itself-then coming to rest. The side of the loom represented inFig. 1, being that at which the shipper-handle'islocated, is the driving side. The magazine containing the reserve weft-supply is located at the opposite sideof-the loom, namely, at the left-hand side in Figs. 2 and 3.

Thedrawin'gs show an application of an embodiment of the invention to a two weftfork loom, although the invention is not necessarily restricted in all instances to'the employment of weft-forks at the weft-detectors.

15 is the weftfork that is employed'at the driving side of the loom, it being mounte'd pivotally upon the rear end of its carrying slide 16, and the latter being supported and guided by the stand 17 fixed upon the breast-beam adjacent the said side. 18 is the actuator (weft-hammer or gooseneck) that cooperates with the said fork 15, the said actuator having the shoulder 18 which. when'the fork 15 is not tilted by the presence of weft or filling between'its tines and the corresponding grid of the lay'when the lay beats up after the pick to the driving-side, engages t-hetail '15 of the said fork-and movesthe slide 1 6 forward'in its guide-stand 17. At 19, Fig. 18, Sheet '2, is the cam by which actuator 18 is moved at the required time tofeel for thetail of the fork 15.

Forward oft-he slide 16 an arm 20 is mounted by 'its'hub 2O (F igs. 2 and 3) loosely'upon a rod or shaft 21extending across the loom in line'with'tripping rockshaft 11. One end of rod or shaft 21 is supported by being entered into the bore of hub or sleeve 12 of finger 12, and the other end thereof is supported by a bracket 22, Figs.

2 and 3, attached to the breast-beam and having a bearing into which such end of the rod "enters. The 'rearwardly extending upper end of the arm 20 is branched, as

shown in Fig. 3, the branches being separated transversely, and in holes made transverselv through the two branchesa pin '23 is mounted, the said pin being fixed in place by means of a clamping screw 24. A portion of the length of the pin projects at the outer side of the arm. The intermediate portion of the pin passes through. the eye of the forward]y-projecting portion of an eyebolt 25 having its threzuled stem screwed into the front portion of the slide 16. The said eye-bolt constitutes a longitudinally adjustable connection between the slide and the pin and arm.

Upon the projecting portion of the pin 2?) an arm 26 shown in detail in Fig. 11, Sheet 3, is hung pivotally. This arm extends forward from the pin, and carries the tripping dog 27, the acting portion of which extends transversely outward above the upper end of an arm 28, shown separately in Fig. 12, Sheet 3, rising from the hub or sleeve 12 which is fixed, as aforesaid, upon the tripping roekshaft 11. Hinged arm 26 has a downwardly-projecting finger 26, which shows most clearly in Fig. 11. If forwardly-acting pressure he applied to this finger it will operate to tilt the arm 26 so as to swing the tripping dog 27 upward above the upper end of arm 28, as in Fig. 16, Sheet 5. A contracting spiral spring 29, Figs. 1 and 3, having its rear extremity engaged with a lateral ear :29 on the rear end of guide-stand l7 and its forward extremity engaged with a downwardly-extend ing ear of the hub-portion of arm 26, aids gravity in causing said arm and dog to tend to swing downward, and also acts with a tendency to draw the weft-fork-carrying slide 16 rearward and hold arm 28 in contact with the front surface of the breast-beam. The upper end of arm 28 is formed with a shoulder 28 see more particularly Fig. 2, Sheet 3, at the rear of which is a pocket 28', the said pocket being partly covered by a lip 28 constituted by a strip of metal which is fastened to the top of the said arm at the rear of the notch and projects forwardly over the latter. The clearance between the front end of the lip and the shoulder is sufficient to permit the dog 27 to pass in and out, and the depth of the pocket at the rear of the shoulder 28* is sufficient to accommodate the dog. Should the dog occupy the pocket as in Fig. 8 at a time when the actuator 18 in moving forward engages by its shoulder 18 with the tail 1?) of weftfork 15 so as to move slide 16, arm 26, and the dog 27 toward the front, the engagement of the said dog with the shoulder 28 will cause the arm 28 to move forward also, as in Fig. 9, turning the tripping rockshaft 11 so as to call the replenishing instrumentalit'ies into action, or throw the shipperhandle so as to arrest the weaving action, or accomplish both results, as the case may be. Normally, however, the dog occupies a position elevated above the shoulder 28, as in Fig. 5, so that in making its first forward stroke it does not engage with the shoulder, and does not take arm 28 with it, but leaves the latter at rest.

WVhen the parts are arranged and combined for three-harness weaving, the time of engi'igcmcnt of the dog 97 with the shoulder 28 is controlled by means of the weftfork 30, 1*igs. 2 and 3, limated at the side of the loom opposite the driving side, namely, the magazine side of an automatic weft-replenishing loom.

31 is the carrying slide of weft-fork $30, and 32 is the guide-stand for the said slide, fixed upon breastl.)eam 2. The eye of the eye-bolt 3 adjustably applied to the front end of the slide 31 is engaged with a projection 34L extending transversely from an arm i l fixed upon the cross-shaft 21, so that as the slide moves forward and rearward in its guide-stand 32 on the breast-beam the said rod or shaft 21 shall be rocked. The actuator (weft-hammer or gooseneck) for the weft'fork 30 is shown at 35, Figs. 2 and 3, and the actuating cam 36 for such actuator is shown in Fig. 13, Sheet 2. Engagement of the shoulder of the said actuator with the tail of the weft-fork $30 as the actuator is swung forwardly by the action of its cam 36, such engagement being permitted in consequence of absence of weft or filling from between the tines of such fork and the grid on the lay as the lay swings forward after the pick of the shuttle from the driving-side of the loom to the side at which :fork 30 is located, will rock the shaft 21. forwardly. As the actuator swings rearwardly again, the slide 31 also is moved in the same direction. and the shaft 21 is rocked rearwardly, through the action of a contracting spiral spring 3(3, which has one end thereof engaged with a fixed car 32 projecting from the rear end 32, and the other end thereof engaged with a screw 3 t" applied to the 'n'ojection 841. on the arm 34:. Spring 36 holds the slide 31. normally in its rearward position. and the arm 34. drawn rearward close to the front surface of the breast-beam. An arm 37 fixed on cross-shaft 21 at the driving side of the loom is thereby held in an elevated position. For three-harness wearing the said arm 37 is provided with a laterally projecting scre\\-stui'l 238, the stem of which is m'ranged to work in a lo1 gitudinal slot 39" in a link tit) having its upper end connected by a pivot 35) (shown best in Figs. 6 and 11, Sheet 3) to the finger 26 of arm 26. By engagement with the wall at the upper end of such slot the said screw-stud lifts the link and the arm 26 with its dog 27, and supports them in an elevated position so long as arm 37, aforesaid, retains its normal elevated position. The normal position of the dog 27, which it occupies while the weft-fork-slidc 3.1 at the n'lagazine side of the loom occupies its normal rearward position, is slightly elevated above shoulder 23 of arm 28, and in of guide-stand contact with the under surface of lip 28, as in Fig. 5, Sheet 8, the dog being pressed upward against the said under surface by the tensile force of the spring 36, transmitted through arm 84, cross-rod or shaft 21, arm 37, screw-stud 38, and link 39, to the arm 26 on which the dog is fixed. To enable the dog to be set to act as required with relation to the other parts, the screwstud 38 is made vertically adjustable upon arm 37 by mounting it adjust-ably in a vertically-elongated slot 37 in the said arm, as shown best in Fig. 4.

The means herein shown for arresting the taking-up action, and letting-back, whenever either weft-detector initially indicates weftdeficiency, comprises the verticallymovable bearing 40, Fig. l, which receives the front end of the worm-shaft 8 and also carries the supporting stud 10 of the detentand let-back pawl 9, the link 41, Figs. 1, 2 and 8, having its lower end pivotally con nected to the said bearing at 42 and its upper end pivotally connected at 43 to a rearwardly projecting arm 44 fixed on the outer end of a short transversely-extending rc-ckshaft 45 mounted in hearings in the stand 11 an arm 46 fixed upon the inner end of the rockshaft 45 and extending upward therefrom with its free upper end in contact with the transverse front surface of the branched upper end of the loose arm 20 which is connected to weft-fork slide 16, a projection 47 extending transversely from arm 46 toward the middle of the width of the loom, and an arm 48 fixed upon cross rod or shaft 21 and extending up close behind the projection 47. Forward turning movement of rockshaft 45 will act through arm 44 and link 41 to raise the take-up worm 7 out of engagement with the teeth of the take-up worm-gear 6, so as to discontinue the driving of the latter and leave it free to recoil to the extent permitted by the detentand let-back pawl 9. This action will take place in the operation of the loom, whichever weft-detector and its slide is initially advanced by the corresponding actuator. The fork 15 and its slide 16 will thus turn the rockshaft 45 by imparting forward movement to arm 20 so as to carry it against the arm 46 of said rockshaft and press the latter arm forward, and the fork 30 and its slide 31 will thus turn the said rockshaft in consequence of the forward turning movement of cross-rod or shaft 21 and its arm 48, causing such arm to engage with. pro jection 47 of the said arm 46 of the rockshaft and press arm 46 forward. lVhichever weft-detector acts first to detect weft-deficiency, it will operate to raise worm 7 out of engagement with worm-gear 6. There after, each time the actuator 35 advances it will advance the weft-fork slide 31 and fur-- ther suspend the taking-up action, and so on shoulder.

Accidents sometimes happen in the case.

of automatic weft replenishing looms employing a change-shaft, as aforesaid, in consequence of the weaver inadvertentlytripping the change-shaft into action while engaged in making adjustments, or in repairing warp or web, after having stopped the loom by hand by throwing the shipperhandle. If the weaver, in turning the loom over by hand, should inadvertently trip the change-shaft into action while his attention is occupied with the adjustments or repairs he is making, and the changeshaft should effectuate the replenishment and then in usual manner restart the weaving instrumentalities of the loom, he might be caught and injured. I employ a safe-guard or safety-device which, when the shipperhandle assumes the position in which the driving power of the loom is unshipped, moves the dog 27 into an inoperative position and holds it there so long as the ship perhandle remains in such position, so that in case the weaver in turning over the loom should bring about an advance of the weftwork 15 and its slide 16 and the arms 20 and 26, the said dog will miss the shoulder 28 of arm 28, and consequently the advancing movement of the dog will have no effect in restarting the loom. To this end, the shipper rockshaft 4 has fixed thereon under the breastbeam a finger 51 having a transversely broadened free extremity adapted for engagement with the finger 26 Thisfinger is so set upon the rockshaft 4 that, while the shipper-handle occupies the position shown in Figs. 1 to 4, into which it is moved for the purpose of shipping-on the driving-power, the said extremity is withdrawn downward and rearward from the said finger, leaving the finger 26 and arm 26 free to swing without interference on the part of the finger 51, and the dog 27 capable of dropping into position to engage shoulder 28 When, however, the shipper-handle is moved to unship the driving-power so as to stop the loom, the turning of the shipper-rockshaft 4 carries the finger 51 around so that its extremity touches the finger 26 as in Fig. 10, Sheet 4, and in case arm 26 is down and the dog in position toengage with the shoulder 28 tilts arm 26 upward so as to raise the (log above the shoulder 28 and against the under side of the lip 28. So long as finger 51 occupies the position in which it is shown in Fig. 10 the dog cannot drop behind the Consequently, ifthe weaver in turning the loom by hand in making adjustments, or repairing the warps or web, should cause the actuator 18 to engage the tail of weft-fork 15 and move slide 16 and arms 20 and 26 forward, no harm can result, because in the uptilted position of the arm 26 the dog 27 will pass forward above shoulder 2t without engaging therewith. I thus avoid danger of injury to the weaver.

The operation, in three-harness weaving, of the devices which have been described, is as followsr-flhe stud 38 is set so that the dog shall occupy normally the position in which it shown in Fig. 5, Sheet 3, and in connection with pick 1 in Fig. 15, Sheet In case failure of weft or filling should take place on the pick from the driving side of the loom to the opposite (magazine) side thereof, so that there is no weft or filling laid in the shed in position to be carried against the tines of the fork 30 at the latter side when the lay heats up following such pick, the said fork will remain untilted. The first portion of the advance of the actuator (weft-hammer or gooseneck) 35 carries it far enough to take hold of the tail of fork 30 and push the slide 31 forward partway. This movement of the slide carries forward the arm 34 of the cross-rod or shaft 21, and turns such cross-rod or shaft so as to lower the arm 37 of the latter and permit the arm 26 and its dog 27 to descend from their normal position shown in Fig. 5, wherein dog 27 is elevated above shoulder 28 and in contact with the under side of lip 28, to their position shown in Fig. 8, Sheet 4-, wherein the dog is in position to engage with the shoulder. This latter position of the dog is represented in connection with pick 2 in Fig. 15. The said turning of the cross-rod or shaft also acts, through the engagement of its upwardly-extending arln 18 with the transverse projection 47 of the arm 4-6 of the rockshaft 45, to turn the said rockshaft so as to cause it, through its connections with bearing M) of the take-up shaft 8, to raise the latter shaft and disengage the worm 7 thereof from the teeth of the worm-gear 6, thereby arresting the take-up and permitting the take-up devices to let-back to the extent allowed by the let-back pawl 9. Meanwhile, the succeeding shed has been opened and the shuttle picked back through such second shed from the magazine side to the driving side. The cam 36 of the magazine side completes the forward stroke of the actuator and the dwell portion of such cam holds the actuator forward, keeping the slide 31 forward and the cross-rod or shaft 21 turned so that the dog 27 remains down in the notch or pocket of the arm 28, and in position to engage with the shoulder 28, as above described. The lay now comes forward a second time and the actuator (weft-hammer or goosencck) 18 at the driving side is advancedby the action of its actuating cam 19, il ig. 13, while the actuator 35 at the magazine side retains its advanced position. There being no weft or filling in the shed to tilt the 'weft'fork 15 at the driving side of the loom, the shoulder 1.8 of the advancing actuator 18 takes hold of the tail i 5 of the said weft-fork, so that the slide 16 on which the said weft-fork is pivoted is moved forward, carrying forward the arms 20 and 26. The forward movement of arm 20 would cause it to act against the arm 4.6, but at this time the latter is being held forward by arm 48 of cross-rod or shaft 12 to continue holding the takeup shaft and its worm 7 in their uplifted position. maintaining thereby the suspension of the takingup action. As the arm 21) goes forward the dog 27, through its engagen'ient with the shoulder 28, acts to more the arm 28 forward, as shown in Fig. 9, thereby turning the tripping rockshaft 11 so as, by means of finger 12, to trip the replenishing instrumentalities into action, and by means of projection 1.3, to trip the shipper-handle so as to unship the driving power of the loom and apply the brake. As the shipper-handle and shipper-rockshaft are turned to effect the said unshipping, the finger 51 touches the finger 26 of the arm 28, turning the latter arm so as to raise the dog 27, lifting it out of the pocket of arm 28, permitting arm 28, as shown in Fig. 10, to swing rearward relative to the dog as shown in Fig. 15 at the beginning of the third pick. The momentum of the loom causes the opening of the third shed and the picking of the shuttle through such shed from the. driving side to the magazine side. and the loom comes to rest with the shuttle in the shuttle-box at the magazine side. It will be perceived that, beginning with the shed which failed to receive a proper weftor filling, and the picking of the shuttle through the said shed and incidental failure of the weft or filling, three sheds have been opened. which is the number comprised in a round of the pattern, and there have been three picks of the shuttle, ending with the shuttle in the shuttle-box at the magazine side. The next shed to be opened, namely. the fourth, is a repetition of the one in which failure of the weft or filling took place. 'Jherefore, the shuttle being in the required box to permit replenishment to be effected. and it being assumed that replenishment has been effected, the first pick following replenishment will be through the said reopened first shed, into which weft will be laid, and consequently the sequence of the pattern will be preserved without anv break due to absence of weft or filling from one of the sheds. As the shipping rocksha ft 11 is automatically rocked to ship on the driving power for the purpose of restarting the 100m, the finger 51 is lowered from its position in Fig. 10 to its position in Fig. 5, out of reach of finger 26. Following the said pick to the magazine side there will be an advance of the actuator 35 at such side, and slide 34 will be moved forward as before, turning cross-rod or shaft 21 so as to lower the arm 26 and dog 27, and also raise the taking-up worm, but the weft that is laid in the fourth shed by the first pick after replenishment will tilt the fork 15 at the driving side so that the actuator 18 will advance idly, and as actuator 35 moves rear ward the dog 27 will be returned to its starting position in Fig. 5, as shown in connection with pick t in Fig. 15, and the take-up worm will be lowered into mesh with takeup gear 6, and the normal action of the 100111 will be resumed.

It will be perceived that the action of the weft-detector devices at the magazine side of the loom in the operation just described is in part to leave the dog 27 free to assume its engaging position sothat when, following the opening of the next shed and the pick from the magazine side, the weft-detector devices at the driving side of the loom operate, impartin forward movement to the said dog, the Cog is effective to trip the replenishing instrumenta'lities into action and also trip the shipper-handle so as to bring about a stoppage of the weaving action for the purpose of enabling the replenishing operation to be conveniently performed. As previously referred to herein, in a loom of the class employing a changeshaft the latter automatically acts to ship on the driving power again and restart the weaving action after the replenishment has been consummated. In case failure of weft or filling should take place on the pick toward the driving side of the loom, the weftfork 15 will remain untilted as the lay beats up. At the beginning of such pick the dog 27 occupies its normal position shown in connection with the unbroken part of pick 1 in Fig. 16, namely above the shoulder of arm 28, and pressing upward against the under side of lip 28. In the advance of the actuator (wefthammer or goo-seneck) 18 its shoulder 18 will engage the tail 15 of the weft-fork 15 and move the weft-fork slide 16 forward, moving forward with it the arms 20 and 26. Arm 20 in going forward will act against the arm 46 to swing the latter forward and turn the rockshaft 15 to arrest the takingup and occasion the letting-back. The front portion of arm 26 is supported normally by the contact of the upper wall of slot 39 in the link 39 with the stem of the stud 38 carried by the arm 37 of the cross-rod or shaft 21, and the upward pressure that is transmitted through the said stud from the spring 36 of weft-fork slide 21 tends to lift the arm and its dog. Consequently, as arm 26 goes forward such arm swings upon the said stud 38 as a pivot, and the dog 27 will advance out from under the lip 28, Fig. 5, passing over the shoulder 28, and assuming in the forward portion of its stroke the elevated position in which it is shown in Fig. 6 and at the conclusion of the first pick in Fig. 16. As soon as the dog 27 clears the lip 28 in its forward movement, the tensile force of the spring 36 will cause the said arm 26 and its dog 27 to rise so that as the actuator18 moves rearward in the loom, permitting the spring 29 to draw the weft-fork slide 16 rearward to its original position, the dog 27 will pass back over the forward end of the lip 28, as shown in Fig. 7, and at the conclusion of the second pick in Fig. 16, and remain there. The second shed having been opened and the shuttle picked therethrough to the magazine side of the loom, the lay comes forward again. The actuator (weft-hammer or gooseneck) 35 being also advanced, the hook of the said actuator takes hold of the tail of the fork 30, which is untilted, owing to the absence of weft or filling from the said shed, and moves the slide 31 forward part way, swinging arm 34- forward and thereby turning cross-rod or shaft 21 and lowering the arm 37 and its stud 38 so that the said stud no longer supports the link 39 and arm 26, leaving the dog 27 resting upon the top of lip 28. The forward turning movement of the cross-rod or shaft 21 also causes its arm 48 to act against the projection 47 of arm 16 tokeep the rockshaft 45 in its forwardly turned position and the taking-up worm 7 disengaged. The third shed having been opened, the shuttle picked therethrough to the driving side again, and the lay caused to beat up, the actuator 18 at the latter side is again caused to advance so as to engage with the tail of the weft-fork 15 and move forward the slide 16 and arms 20 and 26 once more. This movement of arm 20 is an idle one because arm 18 of cross-rod or shaft 21 is at this time acting against the arm 46 to continue the suspension of the taking-up action. The said forward movement of arm 26 carries the dog 27 forward from the lip 28, and as at this time arm 37 and its stud 38 are depressed the dog is permitted to drop upon the extension of the arm 28 in front of the shoulder 28, as shown at the conclusion of pick 3 in Fig. 16. As the actuator 18, slide 16, and arms 20 and 26 move rearwardly again, the dog 27 passes into the pocket 28" of the arm 28 under the lip 28. As cam 36 releases the actuator 35, permitting it to move backwardly to allow spring 36 to draw weftfork slide 31 rearwardly, such spring operates to cause stud 38 to be raised so that it acts upwardly against the upper end of the slot 39 of link 39, and presses the dog 27 upward against the under side of lip 28 as in Fig. 5, and as shown at the beginning of pick 41, Fig. 16. Following the opening of the fourth shed, the pick of the shuttle back from the driving side through such shed to the magazine side, and the beat-up of the lay, the actuator 35 at the magazine side comes forward once more. engaging the tail of the untilted fork 30, advancing the slide 3.1, and again rocking the cross-rod or shaft 21 so as to lower the stud 38 and permit thz arm 26 and its deg 27 to descend from their position in Fig. 5 to their position in Fig. 8, and also at the conclusion of pick t in Fig. 16. The arm 48 also acts against projection 47 of arm l6 to lift the taking-up worm 7 again. Following the opening of the fifth shed, the pick of the shuttle theretlmmgh from the magazine side to the driving-side, and the advance of the lay in beating up, the actuator 18 advances, takes hold of the tail of the weft-fork 1.5, moving forward the slide 16 and arms 20 and 26 once more, the arm 20 again acting idly, and in this advance of the arm 26 the dog 27, being permitted. to engage with the shoulder 28, acts against the said shoulder to carry forward the arm 28 as in Fig. f), and at the conclusion of pic i in Fig. 16, turning the tripping reekshaft 11. and thereby tripping the replenishing instrumtmtalities into action, and also tripping the shipper-handle to arrest the weaving action, the turning of the shipperha'ndle and its rockshaft causing linger 51 to disengage the dog 27 from the shoulder of arm 28, permitting such arm to swing realwvard relative to the dog as at the begiw ning of pick 6 in Fig. 16. The mol'nentum of the loom keeps the weaving instrul'nentalities in motion until the sixth shed has been opened and the shuttle picked there through from the driving side to the magazine side. when the parts come to rest with the shuttle in the shuttle box at the nmgazine-side of the loom, in readiness for enabling the first pick after replenishment to take place from such side through the seventh shed. which is a reopening of the shed in which failure took place. Consequentlv, the weaving resumed without break in the pattern. The automatic turning of the shipper rockshaft 11 to bring about the resumption of weaving will lower finger 51 to its nori'nal position in Fig. 5. the dog remaining in its normal position shown in connectitm with pick 7 in Fig. 16.

For five-harness weaving I remove the screw-stud 38 and thereby deprive the weftdetector (30) at the magazine side of the loom of its control over the dog. This does not interfere with the control of such weftdetector over the taking-up and lettingback. I may also. and in practice preferably will, remove the link 39. Also, as shown by Fig. 1-1, Sheet 5, I adjust the curved safety-linger 5.1 by means of its clamping screw 51 around somewhat upon the shipper-rockshaft t into a position thereon which will enable such linger by its engagement with the linger E26" of arm 26, when the dog 27 in advancing has carried forward the arm 28 and caused the shipper to be moved to unship the driving power, to tilt the arm 26 high enough to raise the dog 27 above the lip 28", so that; as the arm 26 and dog :27 move rearward after having been thus raised, the dog will pass back on top of the lip.

Assuming the parts to be arranged as just described for live-harness weaving and the shipper rockshaft 11 to have been turned to lower the linger :11 the operation is as follows :Tn case failure of weft or filling should take place on the pick from the driving side of the loom to the magazine side thereof, the weft-fork 30 will remain untilted as the lay beats up. By the engagement of the advancing actuator 85 with the tail of such fork the slide 81 will be pushed forward, the arm 3 L will be swung forward and the cross-rod or shaft 21 will be rocked, so that by means of its arm 48, acting against the transverse projection 47 of the arm 46 of the rockshaft 4-5, the latter rockshaft will be rocked to arrest the taking-up and effect the letting-back. The second shed having been opened and the shuttle picked therethrough from the magazine side to the driving side, the lay :ulvances a second time but the fork 15 remains untilted. The advancing actuator 18 at the drivin side takes hold of the tail of the weft-fork 15, moving forward the slide 16 and the arms 20 and 26. This forward movement of the arm 20 is an idle one. As arm 26 moves forward the dog 97 goes forward off the end of the lip 28 its the actuator 18, slide 16, and arms 20. 26, move rearward again in the loom, the dog 27 passes back under the lip 28 into a position correspomling with that occupied by it in Fig. 8. The third shed having been (mened. the shuttle picked there through from the driving side to the magazine side. and the lay caused to beat-up, the

same action of the fork at the magazine side, etc... is repeated, and the suspension of the taking-up is continued. The fourth shed having been opened, the shuttle picked therethrough from the magazine side to the driving side. and the lay caused to beat-up, the weft-fork 15 remains untilted as before and is engaged by the advancing actuator 18, and the slide 16 and arms 20 and 26 are advanced again. This time the dog "27 acts against the shoulder 91 of the arm 28 and carries the said arm forward, turl'iing the tripping rockshaft It and tripping the replenishing instrumentalities into action and also tripping the shi 'iperdiandle to unship the driving power. The loom continuing to run for an interval under momentum, the fifth shed is opened and the shuttle is picked through such shed to the magazine side and remains in the shuttle-box at such side when the loom comes to rest. The shuttle is now in proper position for replenishment and to be picked through .the sixth shed after replenishment, the

sixth shed being a reopening of the first, z'. 6., the one in which failure of filling or weft occurred. As theshipper-rockshaft is turned to effect the shipping, which turning occurs almost instantaneously and while the actuator 18, slide 16, and arms 20 and 26 are in the forward position into which they have been moved, the finger 51 flies up into contact with the finger 26*, and strikes the arm 26 upward so as to raise the dog 27 higher than the front end of the lip 28. As now the said actuator, slide, and arms move rearward in the loom, the dog 27 automatically resumes its starting position on top of the lip 28. In case failure of weft should take place on a pick from the magazine side to the driving side, the actuator 18 at the latter side, in its advance following the beatup of the lay after such pick, will engage the untilted fork 15 and move slide 16 and arms 20, 26, forward, carrying dog 27 forward from the top of the lip 28 so that'it drops upon the forward portion of the head of arm 28, and causing the take-up worm to be raised to arrest the taking-up and effect the letting-back. The rearward movement of the said actuator, slide and arms will carry the dog back under the lip 28 so that it will drop behind shoulder 28, and also lower the take-up worm. Following the opening of the second shed, the pick from the driving-side to the magazine-side, and the beat-up of the lay, the actuator 35 in its advance will engage the tail of the untilted Weft-fork 30 and move slide 31 and arm 34;, rocking cross-rod 21 and raising the take-up worm again, holding it elevated for a time. Following the opening of the third shed, the pick from the magazine-side to the drivingside, and the beat-up of the lay, the actuator 18 will engage the tail of the untilted fork 15 and moving slide 16 forward as before will cause the dog 27 to act against the shoulder 28 of arm 28, so as to turn the tripping rockshaft 11 and trip the replenishing instrumentalities into action and also trip the shipper-handle to unship the driving-power. The momentum of the loom causing the opening of the fourth shed, and the picking of the shuttle therethrough, the loom will come to rest after the fourth pick with the shuttle in the shuttle-box at the magazine side, in readiness for replenishing. The first pick after replenishing will be through the fifth shed, such being a reopening of the fifth shed of that repeat of the pattern which had just been completed prior to the failure of weft or filling. Consequently, two picks of weft will be contained in such shed, although for a portion of the width of the cloth such two picks may be separated by an intervening portion of a pick of weft contained in that portion of the first shed which received a portion of the pick that failed. This irregularity, however, will not be conspicuous in goods woven in a sateen weave with five harnesses, and as it will not occur very frequently the goods will not be marked down in quality on account thereof.-
